I hope you can use this as a reference for when you get confused
about who is related to who and how they are related. Some versions of
the story may use a variation of this scheme, but these are the relationships
of the major characters as represented in what I consider the two "definitive"
versions of the Arthurian legend: Malory's Morte D'Arthur and T.H.
White's The Once and Future King. --Jalynka
